MEP analyze - error

YoavG88H3Z — Sun, 16 Jul 2023 08:12:35 GMT

Hello everyone !

I need help in solving this error message :

"SA 1583: It is not possible to calculate the flow since there is inline equipment that is configured as end of line. Please check equipment in this system and make sure that the equipment connectors used inline have a global system classification and a calculated flow configuration. Global equipment connectors used inline should always be linked to each other."

(I'm Trying to produce a pressure drop report for the ductwork)

That message describes what Revit needs in order to do the analysis, pretty clearly.

Have you checked all your inline equipment? (I've seen VAVs incorrectly categorized as air terminals.)

YES, I have been tried to change it to global connector but still I got that error.

Make sure the damper is a Duct Accessory.

Part Type "Damper".

Make both connectors Global.

Set them as bidirectional.

Set their flow configuration as Calculated.

Link the connectors.
